an easy task for them. They love learning multiplication tricks.
WE WILL LOOK AT A FEW EXAMPLES OF THESE.

12. THEY PROBABLY ALREADY KNOW….
When you multiply any number by zero, the answer
is zero. E.g. (100 X 0 = 0)
Multiply any number by 1, the answer Is that
number. E.g. ( 200 X 1 = 200)
Three times tables is mostly no hard for learners to
remember.
